Deuteronomy 23:23 Meaning and Commentary

Deuteronomy 23:23

That which is gone out of thy lips thou shalt keep and
perform
Which were in their power to perform and lawful to do; and this is observed to make them watchful and cautious, and not be rash in making vows, since, when once they were made, an exact and rigid performance of them was expected; see ( Ecclesiastes 5:4 Ecclesiastes 5:5 ) ;

[even] a freewill offering, according as thou hast vowed unto the Lord
thy God, which thou hast promised with thy mouth;
be it what it will, as to the matter of it, it was to be paid, and in the manner as it was vowed and promised. Aben Ezra observes, that every vow is a freewill offering, but not every freewill offering a vow; the Targum of Jonathan enumerates the several things to be performed, sin offerings, trespass offerings, burnt offerings, and oblations of holy things, and drink offerings, and gifts of the house of the sanctuary, and alms to the poor.

Deuteronomy 23:23 In-Context

21 When thou hast made a vow to the Lord thy God, thou shalt not delay to pay it: because the Lord thy God will require it. And if thou delay, it shall be imputed to thee for a sin

22 If thou wilt not promise, that shalt be without sin.

23 But that which is once gone out of thy lips, thou shalt observe, and shalt do as thou hast promised to the Lord thy God, and hast spoken with thy own will and with thy own mouth.

24 Going into thy neighbour’s vineyard, thou mayst eat as many grapes as thou pleasest: but must carry none out with thee:

25 If thou go into thy friend’s corn, thou mayst break the ears, and rub them in thy hand: but not reap them with a sickle.
